JAMES Y. BOWSEB AND EMERY 1P. BOWSER, OF KITTANNING, PENNSYLVANIA.

v and Earner P. Bowsna, citizens of the United States, residing at Kittanning, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Clamps, of which the following is a specification.

clamp which is intended to bev placed about a finished pipe before the pipe is placed in a vise so that/ the pipe will -be prevented "from being niarred or injured by the vise jaws when the jaws are tightened.

The principal object of the invention is to so connect the two-sections of the clamp th t they will be slidably and pivotally conn'ected together 'and thus adjusted accordthe sectidns will not contact at one This invention is illustrated in the accom- 2s ing to the s'izeof the pipe.

Another object of the invention is to so connect the two sections of the clamp thzlit sic e whenin an operative position. a

panying drawings whereini Figure l is a view showing the :clamp applied to a pipe whichis shown in section and positioned between the jaws of a vise, the jaws being broken away; Fig. 2 is a top plan view of the structure shown in Fig. 1 with the pi e removed-{Fig 3 is a view of one of the ections of the clamp.

The clamp comprises the two sections 10 which are curved transversely so' as to conform to the contour'of the pipe 11 and have their engaging faces covered with fabric strips 12 whichare secured to the sections 10 by anysuitable means. Ears 13 extend from the lower edges of the sections 10 and are provided with longitudinally-.extending slots 1 L so that a pin 15 may be passed through the ears 13. These ears 13 are placed in the relation shown in Fig. 2 and it will thus be seen that the two sections'may be drawn apart by a sliding movement and may also be moved pivotally. It willalso be noted that the ears 18 are provided with flat lower faces so that if the clamp is placed in a flat vise, the ears will form a flat support ongaging face for the clamp.

When using this clamp, it is placed about the pipe 11 and is then placed between the Specification of Letters Patent. Application filed larch 21, 1914. Serial No. 826,459.

jaws 16 of the vise.

CLAMP Patented June 23, 191.4.

The jaws are then brought together and the pipe can be prevented from turning without any danger of its being marred or bent; It is obvious that if the clamp is placed in a vise having vertically moving jaws instead of horizontally moving jaws as shown in the drawings, the

p clamp will-be turned to extend at right This invention relates to an improved angles to the position shown in Fig. 1 with the ears 13 extending vertically instead of horizontally.

W'e have thus provided a pipe clamp which can be adjusted by sliding and pivotal movement, and which is so constructed that'the pipe may be securely held in a vise Without danger of the pipe being injured.

What is claimed is:

1. A clamp comprising a air of sections, hinge ears extending from s id sections and provided with longitudinally extending slots, and a pin passing through the slots of said hinge ears to slidably and pivotally connect said sections.

2. A clamp comprising a plurality of sections provided with curved pipe-engaging faces, cushion means upon the pipe-engaglngfaces of said sections, ears extending from saidsections and provided with longitudinally extending slots, and a pin passing through said slots to slidably and pivotally connect said sections.

3. A clamp comprising a plurality of sections, ears extending from said sections, and means forslidably and pivotally connecting saidsections. A

4. A clamp comprising a plurality of sections, and means for slidubly and pivotally connecting said sections;

A clamp comprising a plurality of sections, and meansi'or' slidubly and pivotally connecting said sections whereby when said C. L. WALLACE, G. A. WALKER.
